(41) At a little before 8 A.M., I went to the nest; its occupant appeared perfectly dry and comfortable. It was B.E., for her mate soon appeared and condescended to take a few worms from hand. I want him to get used to the presence of others when I feed him, so I had Julio (pronounced Holio by himself and friends, instead of Hoolio, as in Spanish) stand along-side me with his glaring white duck trousers. Green-eyes, drawing upon all of his resolution, emerged from the shadows in spite of Julio's brilliant counter-illumination of the landscape, and took a few worms. However, he held his feathers tightly compressed while he did it and was ready to dart into the b bushes if anybody so much as winked. These birds are very deceptive in size. They look bigger 20 feet away than when only 20 inches off. Across the glade they are as big as magpies, but when near at hand, only about half as big. Protean I think that part of this effect is due to the fact that, close by, they are more alert, with feathers held close to the body. Further off, when relaxed and fully at ease they are fluffed out more. This habit of theirs has made it difficult to determine which is the larger of the two, as they do not usually perform their cyclic changes in synchronism.

Both birds look perfectly dry as to bodies, but both of them have the uppermost tail feathers somewhat wet, so that the shafts
